material he had so industriously collected for this work is an 

 irreparable loss to botanical science, for no other hand, in this 

 generation at least, will be able to take up this family where he 

 has left it." We meet everywhere in his works the same com- 

 pleteness and thoroughness, which has induced one of his biogra- 

 phers to say that "nothing of importance is yet to be added to 

 what he modestly styles 'his notes.' " There are written by him 

 numerous papers on other families and species of plants, the 

 Yucca, the Agave, Juncus, Sagittaria, Nelumbium luteum, 

 Callitriche, the Coniferas, the American Oaks, and many pthers 

 which are of great importance for the elucidation of his persever- 

 ing and conscientious labor, but which cannot be enumerated 

 here. However, his publications on the North American Vines 

 should be particularly mentioned, for they have become very 

 important to the grape-grower of this country as well as of 

 Europe. The opinion of his followers as regards his literary 

 qualifications seems to me best expressed in the language of his 

 life-long friend, Dr. A. Wislizenus : "He was firm and decided. 

 He did not rely upon speculations in his scientific researches, 

 but on facts only, ascertained by severe and searching studies. 

 He was strictly true in scientific matters." 



A list of Engelmann's botanical papers has been published by 

 Prof. C. S. Sargent, an old friend and associate, in '• Coulten's 

 Botanical Gazette" for May, 1884; this has been republished 

 with additions, in "Der Deutsche Pionier," by H. A. Rattermann, 

 at Cincinnati, who enumerates 112 entries, and also counts 38 

 scientific societies of which Dr. Engelmann was duly elected a 

 member. 



Our esteemed and munificent fellow-citizen, Mr. Henry Shaw, 

 has caused a collection to be made of all the literary writings of 

 Dr. Engelmann, which will be edited by Prof. Asa Gray, of 

 Cambridge, with the assistance of Prof. William Trelease, of our 

 own Washington University.
